Receive Counter

Some receive counter are defined. The Rx message counter counts all successful received messages (indicated by the CAN controller). If a new received message overwites an old one, so that the old one get lost, increase the Rx overrun counter. If there is a FIFO in the application and a new received message can't be stored in the FIFO, increase the Rx overflow counter. The Rx max. counter indicates the maximum number of messages in the FIFO (max. fill level since the last counter reset). Rx FIFO size is the size of the FIFO.

Transmit Counter

Some transmit counter are defined. The Tx message counter counts all successful transmitted messages (indicated by the CAN controller). If there is a FIFO in the application and it gets completely full, increase the 'Tx overflow counter. If the application loose a message because of a full FIFO, increase the Tx overrun counter. The Tx max. counter indicates the maximum number of messages in the FIFO (max. fill level since the last counter reset). Tx FIFO size is the size of the FIFO.
